License Management (MATLAB Installation Guide for Unix)

MATLAB Installation Guide for Unix

License File

A License File is an ASCII text file, named license.dat, that contains a set of valid license passcodes. When you purchase MATLAB or other products, The MathWorks sends you license information in an e-mail or fax. You must create a License File containing this license information. (For more information about creating a License File from this message, see Before You Install.)

The following is an example of a user-created license.dat file.

# MATLAB license passcode file for use with FLEXlm 6.1g
# LicenseNo: 123     HostID:170a3472
INCREMENT TMW_Archive MLM 12 01-jun-2001 0 EC2889409F00E6230A02 \
  VENDOR_STRING="3" HOSTID=DEMO SN=123
INCREMENT MATLAB MLM 12 01-jun-2001 1 CC98B9F0B9B5A75B38BC \ 
  DUP_GROUP=UH SN=123
INCREMENT SIMULINK MLM 12 01-jun-2001 1 BCE8A9C0759F3C0FB744 \
  DUP_GROUP=UH SN=123
# END---------cut here-------CUT HERE-------END

Each INCREMENT line has the form

INCREMENT product MLM 12 expir-date users passcode license_num

The INCREMENT line containing the TMW_Archive identifies the products you are licensed to install.

Note In previous releases, The MathWorks used FEATURE lines to encode license passcode information in License Files. INCREMENT lines perform the same function as FEATURE lines.

License File Processing

During the installation process, the installer processes the License File, adding information about the name, location, and port number of the license manager daemon. After processing the License File, the installer moves it into the $MATLAB/etc/ directory.

The following is a sample of a processed License File.

# MATLAB license passcode file for use with FLEXlm 6.1g
# LicenseNo: 123    HostID: 170a3472 
SERVER myserver 170a3472 27000
DAEMON MLM /usr/local/matlabr12/etc/lm_matlab 
INCREMENT TMW_Archive MLM 12 01-jun-2001 0 EC2889409F00E6230A02 \
  VENDOR_STRING="3" HOSTID=DEMO SN=123
INCREMENT MATLAB MLM 12 01-jun-2001 1 CC98B9F0B9B5A75B38BC \ 
  DUP_GROUP=UH SN=123
INCREMENT SIMULINK MLM 12 01-jun-2001 1 BCE8A9C0759F3C0FB744 \
  DUP_GROUP=UH SN=123
# END---------cut here-------CUT HERE-------END

Note the addition of two lines to the License File:

SERVER line
DAEMON line

The SERVER line identifies the system on which the license manager daemon runs, by hostname and hostid, and specifies the TCP/IP port number used to connect to it. The SERVER line has this general format.

SERVER hostname hostid TCP_PortNumber

You typically do not need to edit this line except if you know the port number conflicts with other software. You can use any port number; however, to run the daemons from a nonroot account, the port number must be greater than 1024.

The DAEMON line identifies the name and location of the vendor daemon. In user-based licenses, the DAEMON line also contains the path of the license options file.
